PROBLEM TO BE SOLVED: To improve lubrication performance at contact parts which rollingly contact with each other. SOLUTION: A rolling bearing includes rolling members and bearing rings or the rolling members and a pair of bearing plates, wherein recesses 3 are formed in the contact parts of the rolling members with the bear rings or the rolling members with the bearing plates and a material 2 of a Young's modulus lower than that of base material of the rolling members is filled in the recesses so that these portions of the lower Young's modulus are easily deformed by oil film pressure, and a dynamic pressure action is generated by dents caused by the deformation.
